摘要

Aspects of the disclosure relate to adjusting a virtual camera's orientation when a vehicle is making a turn. One or more computing devices may receive the vehicle's original heading prior to making the turn and the vehicle's current heading. Based on the vehicle's original heading and the vehicle's current heading, the one or more computing devices may determine an angle of a turn the vehicle is performing and The one or more computing devices may determine a camera rotation angle and adjust the virtual camera's orientation relative to the vehicle to an updated orientation by rotating the virtual camera by the camera rotation angle and generate a video corresponding to the virtual camera's updated orientation. The video may be displayed on the display by the one or more computing devices.

Similarly, as the vehicle 100 progresses along the turn, the difference between the initial heading 903 and the latest heading 1101, as shown in FIG. 11, may be input into the rotation table and a camera rotation angle may be output. The virtual camera system may then rotate the virtual camera 701 by the output camera rotation angle, thereby causing the field of view of the virtual camera 701 to also rotate by the camera rotation angle to show a third field of view 1120, as further shown in FIG. 11. The determination of the difference between the initial heading 903 and the latest heading 1101 may occur every hundredth of a second, or more or less. Upon completion of the turn by the vehicle 100, the virtual camera 701 may return back to the default position, thereby capturing field of view 1220 as shown in FIG. 12.

The virtual camera system may begin to rotate the virtual camera at a predetermined distance before the vehicle makes a turn. In this regard the virtual camera system may determine an anticipated angle of an upcoming turn of the vehicle based on the vehicle's projected trajectory. For example, the virtual camera system may monitor the vehicle's projected trajectory and the positioning of the vehicle to determine a distance the vehicle is from the upcoming turn and the anticipated angles of the turn the vehicle will be making. The virtual camera system may compare how far away a projected turn is to a predetermined distance. Upon the virtual camera system determining the projected turn is located at or less than the predetermined distance, the virtual camera system may begin to rotate the virtual camera through camera rotation angles corresponding to the anticipated angles of the turn.
